10 Claims. 1

Thi invention relates to new and useful improvements in calendar clocks.

More particularly, the. present invention proposes an improved calendar clock having a stand ard clock movement either spring wound or electric driven and means to indicate the day of the week and the date, the parts for which can be stamped almost entirely from sheet material for inexpensive fabrication and assembly.

Another object of the present invention proposes forming the calendar clock with a simple calendar mechanism positively driven without cast, forged or cut gears. I

Still further, the present invention proposes constructing the calendar clock with a. face having day-of-the-week and date openings and rotatable day of the week and date discs behind the openings with springs to bias the discs in proper position for the indicia thereon properly to appear in the openings without marring the discs or impeding their movements.

For further comprehension of the invention and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 9 is a sectional view taken on line 9-9 of Fig. 2.

Fig. 10 is a fragmentary detail view of the backing plate shown in Figs. 7 and 8.

Fig. 11 is a sectional view taken on lines lll I of Fig. 10.

Fig. 12 is an enlarged sectional view of a portion of Fig. 10 illustrating the interaction of the discs.

Fig. 13 is a fragmentary view of the lower part of the rear side of the face plate.

The calendar clock of the present invention has a casing I5 and a face plate l6 calibrated and numbered in the usual manner with an hour hand IT, a minute hand I8 and a sweep or secand hand IS. A glass 20 covers the face plate l6, being held to the casing l5 by a retainer ring 2|.

Face plate I6 has a central opening 22 (Figs. 7 and 8) a date opening 23 (Fig. 2) and a dayof-the-week opening 24. On the rear side of the face plate It, a disc 25 is rotatably mounted and centrally disposed.

The central disc 25 has a central opening 26 (Fig. 7) to receive a grommet 21, the grommet being frictionally held in the central disc 25 as by a force fit. The grommet 21 also passes through the central opening 22 in the face plate I 6 and is rotatable therein. The central opening 26 in the disc 25 and the grommet are polygonal shaped and the grommet is headed over at one end over the front side of the face plate l6 and at the other end over the rear side of the central disc 25 rotatably to secure the disc to the face plate.

Central disc 25 has six equally spaced peripheral projections 28 and preferably is formed by stamping from sheet metal although the disc may be molded of plastic or metal if desired.

A second or coupling disc 29 i similarly rotatably mounted on the rear side of the face plate i6 adjacent the central or first disc 25. The coupling disc 29 has a single peripheral projection 30 and a centrally concentric circle of twelve lips or abutments 3| equally spaced apart and disposed for engagement by the peripheral projections 28 on the central disc 25. The circular disposed lips or abutments 3| engage with the projections 28 on the disc 25 to rotate the coupling disc 29.

A day-of-the-week disc 32 is also rotatably mounted on the rear side of the face plate l6 overlapping the coupling disc 29 and partially overlapping the central disc 25. The day-of-theweek disc 32 is divided into seven equal segments and has seven peripheral projections 33 equally spaced apart. Consecutive day-of-the-week indicia 34 are disposed on the disc 32 between the peripheral projections 33 and disposed for travel beneath the day-of-the-week opening 24 in face plate l6.

Seven downstruck lips or abutments 35 on the disc 32 are radially aligned with the peripheral projections 33 and extend from the day-of-theweek disc disposed for engagement by the single and 38 (Fig. 8), respectively, adjacent the date,

opening 23 in the face plate. Back plate 36 has upstruck peripheral spacer or spacing ears 3 3((Fig, l1) and the face plate 16 has spacing, ear,receiving peripheral openings 39' in order'for the back plate to hold the face plate; spaced from it. A. stud 46 extending through the aligned openings 3'! and 38 provides means to hold the face plate against the back plate ears 39 as does the retainer ring 217 A: spring. 411: on.- the front-of: the face plate l6 below'thei stud: 46* biases the stud upwardly-L Securedto: the. back plate: 3% is a clock" movement 6?. electrically drivena but which can be spring wound if desired;v Any standard: move-- merit beused. Bac'l'c plate: 355. also has a con-- trai opening s3 (Fig.1 8*):- through which the; central shaft 4:3 of the clock movement 42 passes-for free rotation. The: back plate 36 and the front plate I 6 do not rotate;

A date disc 55 h'avi'n'g acentral shaft opening at is freely rotatable on the shaft 44 between: the back plate 36 and the face plate ['6 and. behind the discs 25, 29 and 32a The date disc ea has thirty-one upstanding abutmen'ts or upstru'clt lips 4W: (-Fig. 2) onits marginal edge portion positioned for engagement with and by the seven peripheral projections 33' on the day-of-tha-wok disc 32 The date disc 55 also has date i'ndicia 4%, from one tcrth-irtyone, consecutively disposed between the marginal edge portion abutments dland underlying, in its path of" travel, the date opening 2 3 in the face plate.

Leaf spring 49 (Figs. 10 and 11) is secured as by welding or soldering to the frontof the back plate 3 3 and provides resilient means to bias the date disc 55 toward the face plate l d-adjacent the date opening 23 in the face plate to insure engagernent of the date disc abutments 41- with the day-of-the-week peripheral projections 33 at this point.

A similar leaf spring 5! (Fig. 13) is secured to the rear side of the face plate Hi providing resilientmeans to bias the day of-the-week disc 32 back from the opening 2 to prevent scraping of the indicia 34 of the day-of the-week disc 32 on the edges of this face plate opening.

The central shaft 44 of the clock movement 42 has an hour hand driving polygonal-shaped portion 5! to conform to the similar shaped central opening 26 in the central or first disc 25' and to central disc 25.

Rotation of the central shafts hour hand driving portion 5 I as the hour hand I"! is moved by the clock movement 42 rotates the central disc 25 each hour through an arc of thirty degrees. Thus each two hours one of the six projections 28 on the central disc 25 moves the coupling disc from one of its abutments 3! to the next. It is thus apparent that in two complete revolutions of the central disc 25, taking twenty-four hours, the twelve-abutment coupling disc 29 will move through one complete revolution.

projection 30 on the coupling disc 29 to complete one cycle of travel and move the day-of-the-week disc from one abutment 35 to the next, thus changing the day of the week appearing in the day-of-the-week opening 24 of the face disc l6. At the same time, one of the peripheral projections 33 on the day-of-the-week disc 32 engages oneof the abutments 41 onthedate disc rotatingthe datedisc through of itSgCilGlllXlfGI'EIlCG. This changes the date to the next higher numeral at.the same time as the day is changed to the next day in the week.

Whilefl have illustrated and described the preferred embodiments of my invention, it is to be r understood" that I do not limit myself to the precise: constructions; herein disclosed and the right is reserved to all changes and modifications comwithin the scope of the invention as defined in the appended claims.
